Lower and upper Hubbard bands: A slave-boson treatment

The Hubbard model is a useful approximation for particles in a periodic potential at sufficiently low temperatures, where all the particles may be assumed to be in the lowest Bloch band, and long-range interactions between the particles can be ignored. See more The Hubbard model is an approximate model used to describe the transition between conducting and insulating systems. It is particularly useful in solid-state physics. The model is named for John Hubbard See more The model was originally proposed in 1963 to describe electrons in solids. Hubbard, Martin Gutzwiller and Junjiro Kanamori each independently proposed it. Since then, it has been applied to the study of high-temperature superconductivity, quantum … See more Although Hubbard is useful in describing systems such as a 1D chain of hydrogen atoms, it is important to note that more complex systems … See more Stacks of heterogeneous 2-dimensional transition metal dichalcogenides (TMD) have been used to simulate geometries in more than one … See more The Hubbard model is based on the tight-binding approximation from solid-state physics, which describes particles moving in a periodic potential, typically referred to as a See more The hydrogen atom has one electron, in the so-called s orbital, which can either be spin up ($${\displaystyle \uparrow }$$) or spin down ( See more The fact that the Hubbard model has not been solved analytically in arbitrary dimensions has led to intense research into numerical … See more WebMar 17, 2024 · LHB, lower Hubbard band; UHB, upper Hubbard band.
